DE RecName: Full=DNA polymerase IV; DE Short=Pol IV; DE EC=2.7.7.7; GN Name=dinB; OrderedLocusNames=TTE0254; OS Thermoanaerobacter tengcongensis. OC Bacteria; Firmicutes; Clostridia; Thermoanaerobacterales; OC Thermoanaerobacteraceae; Thermoanaerobacter. OX NCBI_TaxID=119072; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=DSM 15242 / JCM 11007 / NBRC 100824 / MB4; RX MEDLINE=21992816; PubMed=11997336; DOI=10.1101/gr.219302; RA Bao Q., Tian Y., Li W., Xu Z., Xuan Z., Hu S., Dong W., Yang J., RA Chen Y., Xue Y., Xu Y., Lai X., Huang L., Dong X., Ma Y., Ling L., RA Tan H., Chen R., Wang J., Yu J., Yang H.; RT "A complete sequence of the T. tengcongensis genome."; RL Genome Res. 12:689-700(2002). CC -!- FUNCTION: Poorly processive, error-prone DNA polymerase involved CC in untargeted mutagenesis. Copies undamaged DNA at stalled CC replication forks, which arise in vivo from mismatched or CC misaligned primer ends. These misaligned primers can be extended CC by polIV. Exhibits no 3'-5' exonuclease (proofreading) activity. CC May be involved in translesional synthesis, in conjunction with CC the beta clamp from polIII (By similarity). CC -!- CATALYTIC ACTIVITY: Deoxynucleoside triphosphate + DNA(n) = CC diphosphate + DNA(n+1). CC -!- COFACTOR: Binds 2 magnesium ions per subunit (By similarity). CC -!- SUBUNIT: Monomer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (Probable). CC -!- SIMILARITY: Belongs to the DNA polymerase type-Y family. CC -!- SIMILARITY: Contains 1 umuC domain.
